configure ssh2 key
configure ssh2 key {pregenerated}
Description
Generates the Secure Shell 2 (SSH2) host key.
Syntax Description
Default
The switch generates a key for each SSH2 session.
Usage Guidelines
Secure Shell 2 (SSH2) is a feature of ExtremeWare that allows you to encrypt session data between a
network administrator using SSH2 client software and the switch or to send encrypted data from the
switch to an SSH2 client on a remote system. Configuration and policy files may also be transferred to
the switch using the Secure Copy Program 2 (SCP2)
SSH2 functionality is not present in the base ExtremeWare XOS software image, but is available as an
additional, installable module. Before you can access any SSH2 commands, you must install the module.
Without the module, the SSH2 commands do not appear on the command line. To install the module,
see the instructions in
Appendix A, “Software Upgrade and Boot Options.”
After you have installed the SSH2 module, you must generate a host key and enable SSH2. To generate
an SSH2 host key, use the
configure ssh2 key
command. To enable SSH2, use the
enable ssh2
command.
An authentication key must be generated before the switch can accept incoming SSH2 sessions. This can
be done automatically by the switch, or you can enter a previously generated key.
If you elect to have the key generated, the key generation process can take up to ten minutes, and
cannot be canceled after it has started. Once the key has been generated, you should save your
configuration to preserve the key.
To use a key that has been previously created, use the
pregenerated
keyword. You are prompted to
enter the pregenerated key. You can use the
show configuration
command to list the previously
generated key then copy and paste it after the
configure ssh2 key {pregenerated}
command.
NOTE
Keys generated by ExtremeWare XOS cannot be used on switches running ExtremeWare images, and keys generated
by ExtremeWare cannot be used on switches running ExtremeWare XOS images.
pregenerated
Indicates that the SSH2 authentication key has already been generated. The
user will be prompted to enter the existing key.
